The law of conservation of mass maintains that in all chemical reactions mass is conserved, this ensures that chemical reactions are balanced.
<h2>What is the law of conservation of mass?</h2>
It is a principle of chemistry that states that the quantities of the masses involved in a given reaction must be constant, that is, the quantity of reactants consumed is equal to the quantity of products formed.
<h3>Characteristics of the law of conservation of mass:</h3>
- The chemical composition of a substance remains constant.
- In a chemical reaction certain coefficients are used to balance the equation and this will allow the number of atoms to be equal on both sides.
Therefore, we can conclude that the law of conservation of mass is the one that holds that, within a closed system, the amount of matter before and after a transformation is always the same.

Answer:
More than soap sc um, hard-to-remove scale or film is often due to hard water. Also, take a good look at your faucets or fixtures.

how many it is you should give only one question
Answer:
3 electrons are gained by one nitrogen atom in the formation of K₃N.
Explanation:
The reaction is as follow,
<span> 6 K + N</span>₂<span> </span>→ <span> 2 K</span>₃<span>N
</span>
Oxidation of K,
K → K⁺ + 1 e⁻
Or,
6 K → 6 K⁺ + 6 e⁻
In oxidation reaction potassium atom transfers one electron per atomn and six electrons per six atoms.
Reduction of N;
N₂ + 6 e⁻ → 2 N³⁻
In reduction reaction one molecule of N₂ gains six electrons and 3 electrons per one atom
The statement about the formation of the solar system that
are true and in a correct order are Gravitational force held the newly formed
planets around the sun; small planetary objects formed; hydrogen and helium
became concentrated in the outer solar system to form the outer planets. The answer
is letter D.
